3、st method2describes a laboratory procedure fordetermining the abrasion resistance of resilient flooring usingan abrader with a grit feeder.31.2 The equipment used in this test method is a modificationof the Taber abraser.The regular abrading wheels are replacedby leather clad brass wheels(rollers).A

5、ploys a rotary,rubbing actioncaused by loose abrasive grit and the two abrading wheels.Onewheel rubs the specimen from the center outward and the otherfrom the outside toward the center.The wheels traverse acomplete circle and have an abrasive action on the rotatingspecimen at all angles.This action

7、 as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.5 This standard does not purport to address all of thesafety concerns,if any,a
